I think that's a good way to go: Put foaf:mbox for your current
address in your file if you're fine with possibly adding to the spam
volume but want to make it easy for your friends to contact you, and
try to keep all foaf:mbox_sha1sum's around for easier merging accross
Only problem is that the spam volume makes us all want to do the opposite...
